Their idea of sharing with you what they like wether you like it or not. They just forgot to ask.
We are not alone in this......animals have body language and sounds to express themselves as well.
Because if people DIDN'T express themselves they would be exploding like little car bombs all over the world... It would be a good way to manage population control but kinda messy too
It's a release to stop them exploding later or a way to show someone you appreciate them or care. ex<x>pression is what connects us to one another.
they likely have less of a need to express themselves and more of a need to get attention and be acknowledged
we're social monkeys,
Because it's how we know we exist.
Why not. It is what makes you unique.
